8" rotor for MX Pro?

I just ordered the Marzocchi MX Pro ETA/TAS from 2006. The online manual specs it for a 6" rotor. I ride a very hilly area, but won't be bombing downhill. I will probably ride for a half-hour downhill on fire roads. My current brakes are Deore hydros modified with 8" Gothic rotors both front and rear. For my use, is there any significant danger in running 8" rotors despite what Marzocchi says?

I have used a 180mm and a 185mm on my old MX and Marathon.... but it already showed some visible flex (stopping my 220 lbs )... a 203mm rotor would be too much and is definitely way over Marz specs.... the 07 MX forks are apparently clear for 180mm, stanchions are still 30mm,l maybe3 they modified the dropouts a bit (or just decided to allow it now)

Correct, the lowers were different for 2006.

As far as that superglue on the broken tab, really not funny. Should be a temp ban, if anything.
